Abstract
Abstract An easy to assemble and disassemble doublewedging sawhorse including a horizontal beam supported by pairs of vertical legs, each pair of legs being separated by a slotted shelf mounted in slots in the legs and wedged therebetween, each pair of legs being connected by a tie rod at a point above the shelf and below the beam, having oppositely tapered angular grooves therein such that the tapered edges and the grooves meet and provide a wedging action which increased the pressure of the legs against the beam as the beam is forced further downwardly.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
173 words
A wedging sawhorse comprising: a. a plurality of pairs of legs having obliquely tapered upper edges, said legs having slots therein located between the opposite ends thereof; b. at least one spacing means securely mounted between said legs in said slots; c. an adjustable tie rod means attaching each pair of said legs at a point above said spacing means; and d. a beam mounted between said obliquely tapered edges of adjacent pairs of said legs, said beam having angular tapered grooves for receiving said obliquely tapered edges therein, said grooves being deeper at the lower end thereof to complement the obliquely tapered edges of said legs, tension between said legs and said beam being adjustable by relative vertical movement therebetween due to said beam being mounted above and spaced from said tie rod means such that as said beam is pressed downward the upper ends of said pairs of legs are moved apart and pivot about the tie rod means with the movement being limited by the width of said spacing means.
Claim 2
Dependent Claim
173 words
A wedging sawhorse comprising: a. a plurality of pairs of legs having obliquely tapered upper edges, said legs having slots therein located between the opposite ends thereof; b. at least one spacing means securely mounted between said legs in said slots; c. an adjustable tie rod means attaching each pair of said legs at a point above said spacing means; and d. a beam mounted between said obliquely tapered edges of adjacent pairs of said legs, said beam having angular tapered grooves for receiving said obliquely tapered edges therein, said grooves being deeper at the lower end thereof to complement the obliquely tapered edges of said legs, tension between said legs and said beam being adjustable by relative vertical movement therebetween due to said beam being mounted above and spaced from said tie rod means such that as said beam is pressed downward the upper ends of said pairs of legs are moved apart and pivot about the tie rod means with the movement being limited by the width of said spacing means.
Claim 3
Dependent Claim
46 words
A wedging sawhorse as defined in claim 1 wherein said tie rod means comprises; a. a threaded stud passing through each pair of adjacent legs; and b. a pair of wing nuts on opposite ends of said stud adjustable to press said legs toward each other.
Claim 4
Dependent Claim
19 words
The wedging sawhorse as defined in claim 1 wherein said beam at said grooves is of a trapezoidal cross-section.
Claim 5
Dependent Claim
150 words
A wedging sawhorse comprising: a. a horizontal beam provided with pairs of longitudinally spaced slots located on opposite sides of the beam and presenting downwardly and inwardly inclined surfaces; b. pairs of legs having inwardly and downwardly inclined surfaces thereon located near the upper ends of said legs and positioned in said slots in said beam; c. adjustable tie rods extending between the legs of each of said pairs thereof at points below the upper ends of the legs and spaced from said beam; and d. rigid spreader means located between the legs of each of said pairs thereof at points below said tie rods and operable to oppose inward movement of the lower portions of said legs upon spreading of the upper portions of said legs in response to downwardly exerted pressure applied to said beam causing said beam to move downward with respect to said pair of legs.
Claim 6
Dependent Claim
150 words
A wedging sawhorse comprising: a. a horizontal beam provided with pairs of longitudinally spaced slots located on opposite sides of the beam and presenting downwardly and inwardly inclined surfaces; b. pairs of legs having inwardly and downwardly inclined surfaces thereon located near the upper ends of said legs and positioned in said slots in said beam; c. adjustable tie rods extending between the legs of each of said pairs thereof at points below the upper ends of the legs and spaced from said beam; and d. rigid spreader means located between the legs of each of said pairs thereof at points below said tie rods and operable to oppose inward movement of the lower portions of said legs upon spreading of the upper portions of said legs in response to downwardly exerted pressure applied to said beam causing said beam to move downward with respect to said pair of legs.
Claim 7
Dependent Claim
27 words
The sawhorse as defined in claim 4 including mating slots in said spreader means and in said pair of legs to maintain approximately 70° angular relationship therebetween.
